Vladimir Zapolskiy c227f127e3 arm: lpc32xx: switch to common clock framework
The change switches NXP LPC32xx platforms to LPC32xx clock driver
powered by common clock framework, this obsoletes mach-lpc32xx/clock.o
legacy clock driver and thus it is removed.

Legacy timer driver mach-lpc32xx/timer.o strictly depends on legacy
clock support, but fortunately an existing LPC32xx clock source and
clock event driver completely replaces it, and thus it can be removed
as well.

Noticeably platform UART driver directly operates on LPC32xx source
control block registers, remove this dependency to avoid overlapping
with common clock framework driver, also this guarantees that UART is
working expectedly.

Roland Stigge c70426f153 ARM: LPC32xx: DT conversion of Standard UARTs
This patch switches from static serial driver initialization to devicetree
configuration. This way, the Standard UARTs of the LPC32xx SoC can be enabled
individually via DT.

E.g., instead of Kconfig configuration, the phy3250.dts activates
UARTs 3 and 5.

Roland Stigge 2707208ee8 ARM: LPC32xx: serial.c: HW bug workaround
This patch fixes a HW bug by flushing RX FIFOs of the UARTs on init. It was
ported from NXP's git.lpclinux.com tree.
